The invention relates to a coupling device for the reversible establishment of a drive connection between a driving unit (13) of a tool turret and a driven unit (46) of a tool receptacle (36) which is attached to the tool turret and in which a machining tool is able to be received, said coupling device being characterized in that, in a coupling position, a drive shaft (14) of the driving unit (13) is engaged by way of its external toothing (32) with an internal toothing of a driven shaft (44) of the driven unit (46), and in that, for a collision-free orientation of the external toothing (32) with respect to the internal toothing, before coupling, an orienting device is used, which passes through parts of the driven shaft (44) and has a control means on one side for the cooperation with the drive shall (13) and an orienting means that is actuable by the control means on the other side, said orienting means being securable to the tool receptacle.
A coupling device for the detachable engagement of a drive connection between a drive unit (13) of a tool turret and an output unit (46) of a tool holder (36, 38) that is attached to the tool turret, where a machining tool may be retained in said tool holder, characterised in that a drive shaft (14) of the drive unit (13) is engaged, in one clutch position, with its external gearing (32) with an internal gearing (64) of an output shaft (44) of the output unit (46) and that an aligning device (66) ensures a collision-free alignment between external gearing (32) and internal gearing (64) prior to coupling, wherein said aligning device (66) passes through parts of the output shaft (44) and is provided on the one side with a control means (68) for interaction with the drive shaft (13) [sic] and on the other side with an aligning means (70), which may be attached to the tool holder (38) and controlled by the control means (68).
