How do I replace the coupling on the Kitchen aid blender KSB540ER0? Do I have to remove the housing? The coupling spins clockwise and counterclockwise so I can't spin it off.
Drill a hole in the rim flange at the top. Engage a screwdriver in the new hole and whack it with a heavy hammer. You are trying to spin the coupling in the same direction it turns when the motor runs. This solution ALWAYS works if you do it right.

The Australian outlets will zap that blender - you need to purchase a 240V to 120V transformer in order to make it work.

The piece that you need is referred to as the coupler. The coupler is a breakway part that is designed to shear and/or wear down in the event that the blender is overloaded. This is to avoid damage to the motor.
The coupler may be purchased individually and is an easy repair that can be done at home. You may purchase the part and access step-by-step replacement instructions at the following link:

Look at the underside of the blade shaft. The metal wing nut on the end of the shaft secures the blade assembly to cream coloured plastic blade base. The wing nut also transmits the drive from the rubber coupling on your blender to the blade shaft. The wing nut has a LEFT HAND thread.
The left hand thread ensures the blade assembly does not unscrew during normal blender use.
Firstly disassemble the blender blade assembly. Place a folded tea towel over the blades and hold the blades firmly. If you do not use a tea towel you may cut yourself.
Grip the wing nut with your other hand and unscrew it CLOCKWISE.
Remove the wing nut. You can now remove the blade from the plastic base.
Put the blade assembly in the new jug and offer up the plastic base from under the jug so that the blade shaft protudes enough for you to install the wing nut.
Screw the wing nut ANTI-CLOCKWISE to secure the blades to the plastic base.
Do not over tighten the wing nut; you may have to replace your jug again at some point.

Someday people will learn that MANY of the stepdown convertors are useful ONLY for hairdriers and devices WITHOUT electronics. ONLY use convertors with a big transformer in them for electronic devices. Yes, they are expensive, but so are repairs. Now on to your problem:
The device was probably an MOV varistor transient suppressor.
Trace the circuit out and if it is across the input lines, try one of the same MOV's you find in the surge plug strips.
If the device blew apaart, there is likely further damage. You may be able to get a whole board from an appliance repair company.
Do testing of the unit with a 150 wat lamp in series with the power line.

I just worked on mine tonight. you have to take the bottom off by removing the four rubber feet and then the four screws under them. Now here's the tricky part; you'll need something to hold the jar coupler (round thing spins the blade). I was able to use a large pair of vice grips with some electrical tape wrapped around the jaws, to keep from damaging the coupler. Then take a slot edge screw driver and back out shaft from the coupler. FYI, the threads are reverse, so you will actually be turning the screwdriver clockwise to remove the coupler.
