1. An electrically isolated coupler comprising:
a drive body made of first metallic material and having a drive end configured to interface with a fastening component, the drive body comprising a first interface portion;
a driven body made of a second metallic material and having a driven end configured to interface with a driving tool, the driven body comprising a second interface portion; and
a torque transfer assembly disposed between the drive body and the driven body to electrically isolate the drive body and the driven body from each other and transfer torque between the drive body and the driven body;
wherein the torque transfer assembly comprises an isolation member made of a non-conductive material and configured to maintain separation between the drive body and the driven body,
wherein the torque transfer assembly comprises a first reinforcement member and at least one second reinforcement member,
wherein the first isolation member engages with the drive body, and
wherein the first reinforcement member engages with the drive body.
