Claim 22:
23. A multi-tier torque enhancing device, comprising:
a torque contact device having radially or axially, or both radially and axially, separated torque contact surface configurations, wherein
at least one of the one or more torque contact surface configurations provides an enhanced torque contact surface configuration comprising a pair of X-axis extending torque contact side walls, of an X-axis extension length, that are spaced apart by L1 along a Y-axis, and a pair of Y-axis extending torque contact side walls, of a Y-axis extension length, that are spaced apart by L2 along an 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 the enhanced torque contact surface having an L2/L1 ratio that is less than 1, and wherein the enhanced torque contact surface configuration is configured to be operated by a torque generation tool or is configured to operate as a torque generation tool,
wherein, relative to an X-Y axes plane that extends through each of the X-axis and Y-axis extending torque contact walls and at a Z-axis location where the X-axis extending torque contact side walls are radially most removed from the Z-axis, a maximum radial extension amongst the four concave contoured surface portions on that X-Y axes plane, that is defined by a radial extension from a circumference falling on end points of one of the Y-axis extending walls to a point on an adjacent-most concave contoured surface portion closest to the Z-axis, is less than at least one of said Y-axis and X-axis extension lengths on that X-Y axes plane,
wherein the concave contoured surface portions span and directly interconnect the respective adjacent ends of the X-axis and Y-axis extending side walls between which the respective concave contoured surface portions extend,
wherein said Y-axis extension length is longer than said X-axis extension length, and
wherein all, or at least a majority, of each Y-axis extending torque contact side wall extends along a straight, or substantially straight, line, and said line extends perpendicular or substantially perpendicular to L2 when L2 intersects with the Z-axis.
