Abstract
An improved connection coupling for providing rotary motion from an electric motor rotor to a load wherein a mechanical coupling element is attached to an end of the rotor and to the shaft of the load. The free end of the rotor includes a cavity which extends axially from the end surface of the rotor inward to allow for insertion of a portion of the mechanical coupling element in the cavity. The walls of the cavity do not contact the portion of the mechanical coupling element to allow this mechanical coupling element to move freely in the rotation direction.
