Claim 26:
27. A torque enhancement device comprising a torque enhancement member that has a Z-axis rotation torque generation tool contact surface configuration defined by Y-axis longer torque generation tool contact side walls, each extending in a Y-axis direction and separated apart by an X-axis length (L2), and X-axis shorter torque generation tool contact side walls, each extending in an X-axis direction and separated apart by a Y-axis length (L1), and four corner recesses positioned between ends of adjacent longer and shorter side walls, the four corner recesses each being positioned radially inward of sections of the surface configuration defining the longer and shorter side walls, and wherein a ratio L2/L1 is at least 50% and less than 100%, and wherein the tool contact surface configuration defines an X-Y axes rectangular configuration that falls on a common X-Y axes plane and that is comprised of linear, or essentially linear, extensions in each of said longer side walls and shorter side walls, and wherein the surface configuration is configured to be operated by a torque generation tool or is configured to operate as a torque generation tool.
