Automate turning of manual rotary switch?

Nope.

Wrap a strain gage around the shaft and measure its resistance change as
the shaft twists, differentially, under it.

Also, I'm pretty sure there are torque sensors which are mounted in
shaft couplings ($$$) which'll do the trick.

You can do it that if you want, many do.

Are you allowed to modify the existing panel in order to mount the
necessary motors, sensors, etc.?


JF

I think so, at least to put some holes in it. There are a few pre-existing
holes that I could use if necessary but not quite in the right place.

Maybe a dirty trick of laser interference on the shaft?

Maybe it does not have to be laser interference, you could just measure
the angular displacement of a couple of pair of optical encoder rings
mounted to the shaft. You can even get sealed versions for dirty
environments.
