Abstract
A magnetic coupling for transferring rotational motion from a prime mover to a load includes reference marks calibrated to indicate torque applied to the coupling during operation. A light source providing intermittent light flashes permits a user to visibly discern the relative rotational position of the reference marks to one another, and thereby determine the torque applied to the coupling.
