surprisingly, it doesnt apear to have a D shape machined into the shaft, instead it appears they have only fitted a shim in place of the butterfly and rely on clamping force alone. Ofcourse there could be a spline hidden amongst those pixels. perhaps @nobody can shed some light.

Correct its just a billet body adapter over a bosch DBW section, 
@BlownCorona no shim just clamps on the shaft, but there is no way its going to come loose, or slip, the force needed to move throttles is stuff all, if it ever need to make enough force to try slip it you have bigger issues

Yeah not much force at all and like you say if you make it slip on the shaft you have bigger issues or even a burn out motor from to much force

Thats very interesting. 

Will look more into that. Looks like a nice compact unit 

If you do end up pulling the trigger I would be interested to hear how it goes, like I said, I found them but never ended up buying or using one.

Should be same as Peugeot 407 and Ford Territory (lol) which might be easier to come by locally.

Also, have you seen the likes of these for the other end?

You might be able to keep your existing pedal and remote mount a cable actuated e-throttle thing.

I have seen them and I would just prefer to lose the accelerator cable all together..

And there's a prius one that could be made to work on a factory pedal
