Anti-rotation device for a rod rotator of a reciprocating rod pumping system

A pumping system, comprising:

• a surface unit;
• a bridle assembly operably coupled to the surface unit;
• a polished rod extending vertically through a center of the bridle assembly between a first side of the bridle assembly and a second side of the bridle assembly;
• a rod rotator connected to the polished rod at a location on the polished rod that is above the center of the bridle assembly;
• and
• an anti-rotation device mounted to the rod rotator, wherein the anti-rotation device comprises:
• an arcuate main body portion mounted to the rod rotator;
• a first laterally extending arm having an end connected to a side of the arcuate main body portion and an opposite end extending adjacent to the first side of the bridle assembly;
• and
• a second laterally extending arm having an end connected to an opposing side of the arcuate main body portion and an opposite end extending adjacent to the second side of the bridle assembly;
• wherein:
• 1) The arcuate main body portion comprises an outer radiused portion and an inner radiused portion, wherein the inner radiused portion comprises opposing left and right mounting tabs extending orthogonally from the inner radiused portion and towards a top side of the anti-rotation device, and wherein the opposing left and right mounting tabs are configured to mount the anti-rotation device to the rod rotator;
• or
• 2) The first laterally extending arm and the second laterally extending arm are misaligned laterally.
