ABSTRACT:
A rotational power coupling consists of drive shaft couplings and stationary housings within which the shafts rotate. One housing has a flange with external threads; the other has a plain flange. A threaded nut engages the threaded flange and draws the two flanges together, locking the housings. The nut is surrounded by a collar which can rotate about it. A handle extends from the collar. The nut has external teeth, and the collar has oppositely directed pawls. When the pawls engage the teeth, the handle may be used to turn the collar.
