  • Allen wrench 207 (not shown in Fig. 8A) is inserted into aperture 818 and engages hex recess 822 of coupling 806. Further insertion of Allen wrench 207 bias advances worm gearing 824 into engagement with spur gearing 805. Then rotation of Allen wrench 207 may apply a torque to drive train component 804 (e.g., armature shaft) and thus PTO-based chuck 214.
  • the user has inserted Allen wrench 207 and applies bias and rotation to engage spur gearing 805.
  • Leaf spring 862 is provided to facilitate over-torque protection. As the user applies a greater and greater torque and the PTO- based chuck does not loosen, further rotation of worm gearing 824 by the user will advance worm gearing 824, further compressing springs 858 and 862 while moving worm gearing 824 out of engagement with spur gearing 805, which limits further torque that can be applied. If worm gearing is disposed to position shown in Fig. 8B, e.g., then maintenance upon manual actuation assembly 800 and/or the PTO-based chuck may be appropriate.
  • Allen wrench 207 and the various corresponding hex recesses X10 may take other configurations, e.g. a Torx driver and corresponding Torx-shaped recess, respectively, etc.
