The mechanism includes a primary load path element having at least one slot. A pin-key within the primary load path element slot allows freedom of movement in a rotational direction orthogonal to a positioning direction. A secondary load path element includes at least one secondary load path element slot. A key is positioned between the load path elements. A compression cam is positioned within an opening in the secondary load path element that defines a grooved cam seat. A tension cam is positioned within the opening in the secondary load path element. The tension cam has a defined pivot and stop. A cam follower rests on lobe surfaces of the cams. The cam follower applies a preload force to both cams opposing the cam's rotation. A push rod is seated in a hole in the cam follower and extends through a respective hole in the secondary load path element.
