You sanded the aluminium side? Or the brown coating? The brown (weared) coating side is facing towards the "legs", if it wasn´t this way, the brown coating doesn´t make any sense. The face you are showing in the second image is the upward side.
It´s a subtype of ultrasonic motor, If I´m not errating it is a traveling-wave motor. Also it is very interesting to see the inside of the ECU for the two motors, packed with HF-electronics:

Hmm, I still don´t understand it!
A question: Is the second photo in post #106 showing the same side of the disc as the photo in post #111? According to the center plastic piece no, but you said that this can be removed and be mount in either way, maybe you turned it from taking first photo to second one?
I´m nearly sure that you messed up with top and bottom side of the disc. What you describe as the "rubber gasket" IMO has to be on the top side of the disc, in the groove. Never on the bottom side, showing towards the stators "feet".
The actuators "feet" definitively must not move on a (relativly soft) rubber surface, if they do so, at movement (take in mind that the feet´s movement is less or more "microscopic") they only will do a massage to the rubber but not move the disc - shaft - steering column. The feet need a hard surface to step on and provoke a movement. OK, in your motor was nothing or very little of the thin coating left, the feet step on. But even stepping on the aluminium surface they should work (maybe not as smooth as with the coating) if there is enough pressure/friction.
The "rubber gasket", I think, is a modification that Toyota/Denso did in a newer series of the motors, maybe to reduce noise/vibration/etc. TSB CP-2020 says "(Mar. 2000) - Tilt Motor and Telescopic Motor lining material has been changed".
See here two photos from when I dismanteled my motor. First photo shows the rotor before taking it off, you can see the groove where in your motor´s one sits the "rubber gasket".

And on this foto you can see the "bottom" side, that one, that is facing towards the stator´s feet.

It seems to me nearly impossible that the disc touches the screws if you mount it the correct way; it only should touch the feet with the outer ring (seen on the photo just above as a thin brown ring).
