A shaft (20) for rotationally coupling a main device (10) to a tubular device (30; 30a) is proposed. The shaft (20) has a first, free end (31) that is introduced into the device (30; 30a). The second end (37) of the shaft (20) can be secured to the main device (10). The shaft (20) has, along its outer circumference, at least a first bearing region (46) for contact in a hollow accommodating region (38) of the device (30; 30a) and at least one torque-transmitting section (50.1, 50.2, 50.3, 50.4) that engages with a torque-transmitting section (39.1, 39.2, 39.3, 39.4) of the device (30; 30a). A securing device (36) for device (30; 30a) is provided on the shaft (20). A locking device (120) is provided on said securing device (36), said locking device, in a locked state, preventing the device (36) from being dismounted and, in an unlocked state, allowing the device (30; 30a) to be dismounted. On the securing device (36) is provided an interlocking device (120) with which the locking device (34) can be locked and unlocked and which is arranged on the first end (31) of the shaft (20). |
