A coupling device for engaging an exchangeable tool support (7) for corotation with a shaft (2) of a motor (1), with the shaft (2) mounting at is driven end a hollow shaft projection (3) for receiving the tool support (7). Alternatively, the tool support (7) can mount the hollow shaft projection for receiving the driven end of the shaft. The shaft (2) and/or the tool support mounts a locking device for securing the tool support (7), and which is actuated by centrifugal force. The coupling device is designed and constructed so as to permit a simple mounting of even heavy tools to the output shaft of the motor, and a reliable connection of the tool and drive.
