An apparatus for sensing torque between mechanical members that are connected by a circular member, the circular member having a center hub, a first annular section disposed about the center hub and having a first element, and a second annular section disposed about the first annular section and having a second element. Relative rotation occurs between the first and second annular sections in proportion to torsional forces exerted between the mechanical members. As the circular member rotates, first and second sensors produce output signals as the elements pass the sensors, whereupon a detector circuit connected to the sensors detects the phase relationship between the first and second signals. That phase relationship indicates the torque applied between the mechanical members.
