ABSTRACT In a harmonic drive assembly of the type having a cup-shaped flexspline with spline teeth radially deflectable about its open end, and a wave generator for imparting a circumferential wave of radial deflection in the teeth. A control ring immediately adjacent to one side of the wave generator and coaxial therewith, said ring being radially resilient in opposition to the deflection wake imposed in the flexspline by the wave generator whereby torsional stiffness of the assembly is enhanced, the localities of contact of the flexspline surface with the wave generator and the control ring being angularly out-of-phase.
