When transmitting torque from a drive shaft to a driven shaft, flexible couplings:
absorb and dampen irregularities in the torque
distribute peak loads
Allow misalignments and offsets between the shafts
Permit some disortions in the mounting beds
Avoid the unwelcome constraints that may occur if a rigid coupling were fitted in the same conditions.
Allow a highter constructions, with wider tolerances, and lower cost.

These torsionally stiff couplings serve for the connection of two shaft ends compensating for angular and parallel misanlignment as well as axial backlash. They are used for the backlash-free and precise angular drive of:
-potentiometers / angle encoders
-resolvers / transducers
-low powered drives
The mounting of the coupling onto the shaft ends is achieved by two set screws each with one cup point per hub. In the case of a smaller than indicated size of bore, an accurate transmission or peak-torque is no longer guaranteed. Larger borings can be supplied on request.
