Patent ID: 7037203

Claim:
An adapter device for adapting a drive of a worm gear to rotate an output shaft, said adapter device comprising: a sleeve having an inside diameter slightly greater than an outside diameter of the output shaft, said sleeve having an outer diameter which is slightly less than an inner diameter of the drive of the worm gear; an elongate key cooperating with a longitudinal slot defined by the output shaft and an aligned channel defined by said sleeve and an aligned groove defined by the drive of the worm gear, said sleeve being disposed between the output shaft and the drive of the worm gear, said sleeve, the output shaft and the drive of the worm gear being coaxial relative to each other so that when the drive of the worm gear rotates, said key interacts with, said aligned groove of the drive of the worm gear, said channel of said sleeve and said longitudinal slot of the output shaft for rotating the output shaft; and a plurality of sleeves, each sleeve of said plurality of sleeves having said inside diameter of a different diameter in order to accommodate output shafts having various outside diameters.
