1. A drive coupling arrangement for transmitting substantially exclusively torque from a drive arrangement to a gear assembly under test, the drive coupling arrangement comprising:

  • a first coupler portion attached to the gear assembly under test, said coupler having a polygonal cross-sectional configuration that extends continuously over a predetermined length of axis, the polygonal cross-sectional configuration having a plurality of substantially planar surfaces that extend parallel to the predetermined length of axis;

    a second coupler portion having an internal cross-sectional configuration that accommodates the polygonal cross-sectional configuration of said first coupler portion, said second coupler portion having a plurality of engagement portions, each of which communicating exclusively with respectively associated ones of a predetermined number of the substantially planar surfaces of said first coupler portion, and being axially translatable along said first coupler portion for a portion of the predetermined length of axis, wherein said first and second coupler portions exert a non-slip torque against one another via the substantially planar surfaces of said first coupler portion and the engagement portions of said second coupler portion, over a predetermined range of the portion of the predetermined length of axis; and

    a resilient insert installed within the second coupler portion for limiting the extent of axial translation between the plurality of engagement portions of said second coupler portion along said first coupler portion.
