Shaft coupling suitable for various low-torque applications. The coupling is gap-free and the turning stiffness sufficient for e.g. pulse sensor operations with 6000 pulses per turn. High tolerance against angle errors, up to 10 degrees. High axial stiffness, making it usable also for pull and pressure movements. Other characteristics are, among other things, that the coupling has low torque of inertia and good damping qualities, is resistant to corrosion, and that it is maintenance-free, electrically insulated and non-magnetic.
