Abstract
A handwheel rotates an improved flexible shaft assembly which causes a socket member to rotate therewith. The socket seats an adapter therein which is uniquely configured to engage tapered square valve stems of different sizes and degrees of taper. The flexible shaft assembly is provided with a ferrule at the handwheel end and another ferrule at the socket end. The casing of the flexible shaft is free-positioning by virtue of the ability of the casing to slowly rotate in the ferrule provided at either the handwheel end, or at both the handwheel end and socket end, thus automatically relieving casing torsional stresses.
