a rotary direction the handle 12 fits over an opening in one end of the bonnet 14 the stem driver 16 is fixed to the handle 12 to rotate therewith by an axial bolt 32 extending outward through the opening in the bonnet 14 the stem driver 16 has a shoulder at an outer end that is larger than the opening in the bonnet 14 so that the bonnet 14 is captured between the handle 12 and the stem driver 16 while both can rotate relative to the bonnet thus once the bonnet 14 is threaded onto the retainer 22 at the inward end of the bonnet it no longer rotates a washer 34 can be inserted between the handle 12 and the bonnet 14 to ease rotation of the handle 12 if desired alternatively a lubricant can be provided at this position and or the materials can be selected to permit sliding contact it should be noted that the stem driver 16 has a squared inward socket this is suitable to axially slidably receive the outer walls of the adapter 18 the adapter 18 is not bolted onto the valve stem rather its internal splines permit no relative rotation between.
