Abstract

A coupling for the torsion-proof, but radially resilient connection of a stator of an angle encoder with a stator of an object to be measured, the coupling includes a spring element that is either normally in a first position but when the spring element is bent out by a bending force the spring element moves from the first position through a click point to a second position where the spring element engages a portion of the angle encoder or the spring element normally is biased in a first position but when the bias of the spring element at said first position is canceled the spring element is moved to a second position where the spring element engages a portion of the angle encoder.
