A passive locking chuck for a rotary driver. The chuck has a pair of rings, one fixed and the other rotatable between a first orientation where recesses formed in the rotatable ring are aligned with recesses formed in the fixed ring, and a second orientation where the recesses are offset from one another. When an upper end of a foundation component having a toothed coupler is inserted into the chuck and rotated axially, the movable ring is moved to the second orientation and the foundation component is thereby captured in the chuck. As soon as resistance is encountered from the soil, the ring moves back to the first orientation so that upon reaching the desired embedment depth, the rotary driver may be withdrawn without counter rotation.

This disclosure includes various embodiments of couplers for coupling intraosseous (IO) devices and drivers, and various embodiments of drivers and kits.

An apparatus in the form of an adapter for forming a connection comprising a first part adapted for coupling with a second part by a quick-release coupling formed by a first projection of the first part having an at least partial dovetail shape and a recess of the second part having an at least partial dovetail shape. An opening in the recess is adapted for receiving the projection in an axial direction. In other embodiments, the adapter is: (1) frictionally enhanced for engaging an internal portion of the drilling element; (2) includes a radial projection elongated in an axial direction for engaging the internal portion of the one drilling element; and/or (3) has a cutter for scoring an internal portion of the one drilling element upon being inserted therein and rotated. An adapter is also disclosed for use with a drill chuck, including for creating a twist lock connection.
