1. A lower rotor assembly for a torque sensor, the lower rotor assembly comprising:
a lower rotor over-mold including at least one first heat staking structure extending from an upper surface thereof and at least one second heat staking structure extending from the upper surface thereof, wherein the at least one first heat staking structure is a plurality of heat staking ribs, wherein the at least one second heat staking structure is a plurality of heat staking posts, wherein the heat staking ribs and the heating staking posts are arranged in an alternating manner around the lower rotor over-mold;
a lower stator integrally formed with the lower rotor over-mold as a single, unitary component; and
an upper stator including:
at least one first receiving structure, wherein each first receiving structure receives a respective first heat staking structure of the lower rotor over-mold when the upper stator is coupled to the lower stator; and
at least one second receiving structure, wherein each second receiving structure receives a respective second heat staking structure of the lower rotor over-mold when the upper stator is coupled to the lower stator.
