A clamp comprises an anvil and a jaw member moveable relative to the anvil between a secured positioned and an unsecured positioned. A driver, which moves the jaw member between the secured and unsecured positions, includes a torque limiter to inhibit overtightening the jaw member against an object.

A clamp comprises an anvil and a jaw member moveable relative to the anvil between a secured positioned and an unsecured positioned. A driver, which moves the jaw member between the secured and unsecured positions, includes a torque limiter to inhibit overtightening the jaw member against an object. The jaw member has a rigid engagement portion and an elastomeric pad on its engagement surface. In the unsecured position, the elastomeric pad projects above the rigid material such that when the jaw member is brought into contact with the object, the elastomeric pad contacts the object and the object is substantially free of contact with the rigid engagement portion. In the secured position, the elastomeric pad is compressed such that both the elastomeric pad and rigid engagement portion contact the object.

What is claimed is: 1. A torque limiting rotary driver mechanism comprising a hand grip, a screw, and a torque limiter including a clutch interconnecting the hand grip and the screw, the clutch having a first clutch element operatively connected to the screw for conjoint rotation therewith and a second clutch element mounting the hand grip and supported by the first clutch element for axial translation relative to the first clutch element between a drive position in which the first and second clutch elements are interlocked for conjoint rotation and a non-drive position in which the second clutch element is rotatable relative to the first clutch element, the torque limiting rotary driver mechanism in combination with a geomatics support and a clamp for attaching items to the geomatics support, the clamp being moveable between a secured position wherein the clamp is secured to the geomatics support and an unsecured position wherein the clamp can be moved relative to the geomatics support, the driver mechanism moving said clamp between said secured position and unsecured position and the torque limiter allowing for the driver to be operable up to a threshold torque and rendering the driver inoperable over said threshold torque, the threshold torque being selected to inhibit overtightening of the clamp against the geomatics support to an extent causing deformation of the geomatics support. 2. The system as set forth in claim 1 wherein the geomatics support is selected from a group consisting of a geomatics pole and a tripod. 3. The system as set forth in claim 1 wherein the drive position of the clutch corresponds to the driver mechanism being operable and the non-drive position corresponding the driver mechanism being inoperable. 4. The system as set forth in claim 3 wherein the hand grip resiliently biases the clutch elements toward the drive position of the clutch. 5. The system as set forth in claim 4 wherein the first and second clutch elements are formed with teeth. 6. The system as set forth in claim 1 wherein the geomatics support is made of fiberglass. 7. The system as set forth in claim 1 wherein the clamp comprises a jaw moveable from an unsecured positioned position wherein the clamp can be moved relative to the geomatics support to a secured positioned position wherein the clamp is secured from movement with respect to the geomatics support, the jaw comprising first and second jaw members engageable with the geomatics support on generally opposite sides thereof for clamping engagement with the geomatics support, the first and second jaw members having respective engagement surfaces shaped at least partially in conformance with the shape of an exterior surface of the geomatics support, the first jaw member having a rigid engagement portion and an elastomeric pad on its engagement surface, in the unsecured position the elastomeric pad projects above the rigid engagement portion such that when the first jaw member is brought into contact with the geomatics support the elastomeric pad contacts the geomatics support and the geomatics support is substantially free of contact with the rigid engagement portion, in the secured position the elastomeric pad being compressed such that both the elastomeric pad and rigid engagement portion contact the geomatics support.
