ABSTRACT:
An adapter device is disclosed for adapting a drive of a worm gear to rotate an output shaft. The adapter device includes a sleeve having an inside diameter which is slightly greater than an outside diameter of the output shaft. The sleeve has an outer diameter which is slightly less than an inner diameter of the drive of the worm gear. An elongate key cooperates with a longitudinal slot defined by the output shaft and an aligned channel defined by the sleeve and an aligned groove defined by the drive of the worm gear. The sleeve is disposed between the output shaft and the drive of the worm gear, the sleeve, the output shaft and the drive of the worm gear being coaxial relative to each other. The arrangement is such that when the drive of the worm gear rotates, the key interacts with the aligned groove of the drive of the worm gear, the channel of the sleeve and the longitudinal slot of the output shaft for rotating the output shaft.
