A coupling device for engaging an exchangeable tool support ( ) for corotation with a shaft ( ) of a motor ( ), with the shaft ( ) mounting at is driven end a hollow shaft projection ( ) for receiving the tool support ( ). Alternatively, the tool support ( ) can mount the hollow shaft projection for receiving the driven end of the shaft. The shaft ( ) and/or the tool support mounts a locking device for securing the tool support ( ), 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.
