<p>At least one catch part extends around the locking part, can be used to fix the latter into position and can preferably be moved along the coupling sleeve in an axial direction. The coupling sleeve is provided with additional rotary drive parts (32, 76, 78). The transmission device (10) is used to releasably connect a head part (54) and a shaft part (56) together. At least one locking part mounted on a coupling sleeve can be engaged with grooves (33, 35) in the ends of the head and shaft parts (58, 60). Independent claims are also included for the following: (1) Power transmission device with the locking parts movable around a coupling sleeve in an axial direction, the sleeve being provided with catch parts for supporting the locking parts in the radial direction and having rotary drive parts fixed to it, the catch parts being rotatably mounted between rotary drive stops; (2) Power transmission device including at least one locking part for connecting each head or shaft part to a coupling sleeve, each locking part being provided with at least two stop surfaces extending in a radially inwards and axial direction for a form-fit connection with corresponding stop surfaces on the sleeve; and (3) Power transmission device with a coupling sleeve for releasably holding the head and shaft parts together via locking parts, the sleeve having a substantially smooth outside surface in both the locking and released positions.</p> |
