ABSTRACT:
The coupling means can be mounted over a rotatable shaft of existing motors and employs a lining sleeve which is disposed about or within the shaft and a helical spring which is disposed between the sleeve and shaft. Various types of couplings are used to secure a hand wheel to one or both ends of the spring such that rotation of the hand wheel causes the spring to bind about the shaft and cause turning of the shaft. In some embodiments, rotation of the hand wheel causes the opposite end of the spring to bind about the shaft to turn the shaft with the hand wheel.
