ABSTRACT:
A stem nut for driving a valve stem is coaxially rotatable within a drive collar which is offset from the axis of a nutating drive motor. The drive motor and the drive shaft are coupled together for rotation by means of readily interchangeable sprockets driven by a roller chain. The coaxial stem nut and the drive collar are releasably locked together by removable pins. When the pins are removed, the stem nut permits the valve stem to be directly operated with a wrench or the like. The stem nut is readily removable from the offset drive assembly by releasing a snap ring.
