A cushion connector (10) used for above ground drilling has pin (11) and box (12) components at opposite ends. A housing (13) extends axially between the pin and box components. A drive spline (22) is operably connected to one of the components and extends outwardly from the axis (23) of the cushion connector (10). A plurality of drive blocks (24) extend inwardly from the inside diameter of the housing (13) and engage with keyways (69) of the drive spline (22). Drive lugs (71) connected to the inside of the housing (13) act on the drive blocks (24) and resilient cushion blocks (70). A spring (30, 60) extends between the pin (11) and box (12) components within the housing (13) and exerts axial force between them. The drive splines (22) are coaxial with the connector (10) and move axially under operation. Cushion blocks (70) are provided between the drive blocks (24) and drive lugs (71).
