An apparatus which may be used to drivingly engage a rotating shaft, reduce the effect of the diametral runout thereof and drive a rotary sensor including a sleeve placed coaxially about the rotating shaft and drivingly engaging the shaft by means of mating splines. Any diametral runout present in the rotating shaft is directly imparted to the driven end of the sleeve. A spherical annular protrusion extends radially outwardly from the sleeve and slidingly engages bore having a central axis coincident with the preferred axis of rotation. In this manner, the center of the spherical annular protrusion, and consequently that portion of the sleeve, is maintained coincident with the preferred axis of rotation. The opposing end of the sleeve drivingly engages the rotary sensor with mating splines. If diametral runout is present in the rotating shaft, the sleeve will gimble about the center point of the spherical annular protrusion. A reduction in runout will be realized which is in proportion to the ratio of the distance from the center point of the spherical protrusion to the driven end versus the distance from the center point to the driving end.
