Patent ID: 8547543

Claim:
An angle-measuring device, comprising: a first group of components including: a hollow shaft adapted to enclose a shaft; a graduation disk secured to the hollow shaft; a connecting element; and a device adapted to affix the connecting element relative to the hollow shaft; and a second group of components including a sensor element adapted to scan the graduation disk; wherein the groups of components are rotatable relative to each other about an axis and a relative angular position between the groups of components is determinable by the angle-measuring device; wherein the hollow shaft and the connecting element are arranged such that the connecting element is operatively connectable with the hollow shaft in a manner that torque is transmittable with positive locking between the connecting element and the hollow shaft about the axis; and wherein the connecting element is movable into a positive-locking position by axial displacement by the device adapted to affixing the connecting element and is radially prestressable against the shaft.
