Are you going to make your torque limiter? If so, make one that's noisy
when operating. I had an industrial sewing maching with a safety clutch
in the form of a spring-loaded ball in the driven member, engaging with
a detent hole in the driven half of a coupling. It made a nice racket
when the machine jammed.

Put a magnet on each half of the limiter, detect both magnets, if one
comes around without the other, shut off, sound alarm.
Requires limiter with only one "Drive" position.
