Abstract
A handle assembly for a rotating shaft which reduces shaft wobble. The handle assembly has a bearing in the form of a split ring which is arcuate in cross section to provide a reduced friction when the bearing is placed between the shaft and a housing axial bore. The handle assembly is employed to engage and rotate the stem of a valve. In a preferred manner, the bearing affords a cavity for a shaft lubricant.
