• wherein the first member defines a plurality of notches, with each one of the plurality of notches disposed between an adjacent pair of the plurality of fingers;
• a second member attached to the first member and axially moveable along the central longitudinal axis relative to the first member in response to rotational movement about the central longitudinal axis;
• and
• wherein:
• the second member includes a protuberance extending radially outward from the central longitudinal axis, with the protuberance positioned within one of the plurality of notches and in interlocking engagement with two of the plurality of fingers to resist rotation of the second member relative to the first member about the central longitudinal axis;
• the second member includes a plate extending radially outward from the central longitudinal axis, with the protuberance disposed on a circumferential edge of the plate;
• and
• the second member includes a shaft having a lower threaded portion engaged with the first member, and an upper connecting portion, with the plate disposed axially along the central longitudinal axis between the lower threaded portion and the upper connecting portion.
