Abstract
A shear coupling includes a first half, a second half, and a shear pin connected therebetween. The connections between the shear pin and the first half and the second half substantially isolate the shear pin from torsional, bending, and compression forces experienced by the first half or the second half. The connections between the shear pin and the first half and the second half transfer tension forces experienced by the first half and the second half to the shear pin from. A tension force above a predetermined threshold causes the shear pin to separate into two pieces that remain connected to the first and second halves.
