Abstract: 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ring moves back to the first orientation so that upon reaching the desired embedment depth, the rotary driver may be withdrawn without counter rotation.
