1. An adaptor for interfacing between an endpiece of a lifting apparatus and a nacelle of a wind turbine, comprising:
a base plate having an outer surface and an inner surface, the outer surface having one or more projections configured to engage the adaptor to the nacelle;
a first side leg extending away from the inner surface of the base plate, wherein the first side leg includes an outer surface, an inner surface, and a first bore extending between the inner and outer surfaces of the first side leg;
a second side leg extending away from the inner surface of the base plate and spaced from the first side leg, wherein the second side leg includes an outer surface, an inner surface, and a second bore extending between the inner and outer surfaces of the second side leg, and wherein the base plate, first side leg, and second side leg collectively define a recess configured to engage the adaptor with the endpiece of the lifting apparatus;
a first set screw positionable in the first bore such that an abutment end of the first set screw is disposed within the recess; and
a second set screw positionable in the second bore such that an abutment end of the second set screw is disposed within the recess,
wherein the first and second set screws are configured to be movable, relative to the first and second bores, respectively, toward and away from each other to adjustably position the adaptor relative to the endpiece of the lifting apparatus.
