This Rotational Electromechanical Converter has current and produces torque, but the ideal motion sensor reports zero. What am I doing wrong?

I can't seem to figure out why the Ideal Rotational Motion Sensor in the following picture will only output zero for W and A. It is especially strange because the Trq_out signal is exactly what I would expect it to be, but it's not stalled - the next torque goes to a Revolute Joint that moves just fine...
Any ideas?
Thank you!

The ideal torque sensor in parallel with the rotational damper does not allow motion. Therefore, not motion is possible between the R and C ports of the ideal motion sensor.
To correct your model, remove the ideal torque sensor in parallel with the rotational damper, and place it in series with the rotational damper.

Thank you Nicolas! I was not fully understanding through and across components for mechanical systems.
Very much appreciated!
