ABSTRACT:
Valve seat grinding apparatus incorporating an improved articulated rotatable torque transferring coupling. The coupling includes torque transfer member in connection with a pair of functionally cylindrical torque members. Each torque member includes a circular torque transfer spline with the axis of spline being disposed perpendicular to the axis of torque member. The spline has an opening of designated internal distance located at one end of torque member and centered with the axis of torque member. A pair of circular torque transfer grooves are defined into torque transfer member which cross at right angles on each side of torque transfer member to form a pair of intersections. The intersections form flat clearance surfaces with the distance between clearance surfaces being less than designated distance of internal diameter of opening. A splineway opening is defined through circular spline and across the axis of one of torque members to accommodate passage of spline of other said torque member of the torque members.
