• a keeper (216), fixed within the first body (217);
• and
• a resilient member (215), captured between the second body (214) and the keeper (216);
• and
• a tool retainer (230), comprising:
• a second threaded portion (233T), configured to be threadably fastened with the first threaded portion (212T) of the first body (217);
• and
• a key (232), fixed relative to the second threaded portion (233T).

A rotary drive (299), comprising:

• a tool (210), comprising:
• a first body (217), comprising a tool-change-engagement portion (212) and, a first threaded portion (212T), fixed relative to the tool-change-engagement portion (212);
• a second body (214), comprising a fastener-engagement portion (211), wherein the second body (214) is translatable relative to the first body (217), co-axially with the first body (217), and is co-axially rotationally fixed relative to the first body (217);
• a keeper (216), fixed within the first body (217);
• and
• a resilient member (215), captured between the second body (214) and the keeper (216);
• and
• a tool retainer (230) comprising:
• a second threaded portion (233T), configured to be threadably engaged with the first threaded portion (212T) of the first body (217);
• and
• a key (232), fixed relative to the second threaded portion (233T);
• a retainer (240), configured to be coupled with the key (232) of the tool retainer (230);
• and
• a socket (220), co-axially rotatable relative to the tool retainer (230) when the retainer (240) is coupled with the key (232) of the tool retainer (230).

A tool (210), comprising:

• a first body (217), comprising a tool-change-engagement portion (212) and a first threaded portion (212T), fixed relative to the tool-change-engagement portion (212);
• a second body (214), comprising a fastener-engagement portion (211), wherein the second body (214) is translatable relative to the first body (217), co-axially with the first body (217), and is co-axially rotationally fixed relative to the first body (217);
• a keeper (216), fixed within the first body (217);
• and
• a resilient member (215), captured between the second body (214) and the keeper (216).

A method (950) of threadably coupling a first fastener (198) with a second fastener (197) using a rotary drive (299) comprising a tool (210), the method comprising:

• rotationally anchoring the second fastener (197) relative to the tool (210) by co-axially urging a fastener-engagement portion (211) of the tool (210) against the second fastener (197) and rotating the tool (210) relative to the second fastener (197) until the fastener-engagement portion (211) of the tool (210) mates with a receiving portion (197R) of the second fastener (197);
• receiving the first fastener (198) within a socket (220) of the rotary drive (299) co-axially with the fastener-engagement portion (211) of the tool (210);
• and
• rotating the first fastener (198) with the socket (220) of the rotary drive (299) relative to a housing (200H) of the rotary drive (299) to cause the first fastener (198) to threadably engage the second fastener (197);
• wherein, when the first fastener (198) is rotated with the socket (220) of the rotary drive (299) relative to the housing (200H) in a first direction to cause the first fastener (198) to threadably engage the second fastener (197) while the fastener-engagement portion (211) of the tool (210) is mated with the receiving portion (197R) of the second fastener (197) to rotationally anchor the second fastener (197) relative to the tool (210) of the rotary drive (299), the fastener-engagement portion (211) of the tool (210) is co-axially translated relative to a tool-change-engagement portion (212) of the tool (210) and relative to the socket (220) of the rotary drive (299).
