Abstract
A lock 7 non-rotatingly and axially secures a coupling sleeve 6 to a power take off shaft 4 or driving journal 5 of a self driving implement or tractor 1. To achieve a clearance free rotatable and axial connection between the coupling sleeve 6 and power take off shaft 4 or driving journal 5, the locking element via at least one locking face 15, at least partially engages an annular groove 12 of the power take off shaft 4 or driving journal 5 to provide a clearance free connection. The locking element may be a bolt 16 with a conical locking face 15 to engage the angular groove 12.
