Claim 9:
10. A multi-tier torque enhancing combination, comprising:
as a first torque enhancing device the torque enhancing device of claim 1, wherein the first torque enhancing device comprises a driver torque contact body having at least two torque driver torque contact surface configurations, with the driver torque contact body having a Z-axis depth or thickness, and wherein at least one of the two torque driver contact surface configurations comprises a pair of X-axis extending torque contact side walls that are spaced apart by L1 along a Y-axis, and a pair of Y-axis extending torque contact side walls that are spaced apart by L2 along the X-axis, as well as four concave contoured surface portions positioned between respective adjacent ends of the X-axis extending torque contact side walls and the Y-axis extending torque contact side walls, and wherein the L2/L1 ratio is less than 1, and
a second torque enhancing device, comprising a recessed recipient torque contact body having at least two torque contact surface configurations with the recessed recipient torque contact body having a Z-axis depth or thickness, and at least one of the two torque contact surface configurations having a torque enhancement surface configuration comprising a pair of X-axis extending torque contact side walls that are spaced apart by L1 along a Y-axis, and a pair of Y-axis extending torque contact side walls that are spaced apart by L2 along the X-axis, as well as four concave contoured surface portions positioned between respective adjacent ends of the X-axis extending torque contact side walls and the Y-axis extending torque contact side walls of the recessed recipient, and the torque enhancement surface configuration has an L2/L1 ratio that is less than 1, and wherein
the first and second torque enhancing devices are configured for torque generation mesh engagement at least at the torque enhancement contact surface configurations of the respective first and second torque enhancing devices.
