The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

An apparatus, having an elongated main body (102) with a dovetail shape, a top surface (104), a bottom surface (106), a side surface (108) connecting the top surface and the bottom surface, a first end (120), a second end (122), and a chamfer (124) at a corner (126) of the side surface and the bottom surface at the first end. A size and shape of the elongated main body matches a size and shape of a frustoconical section (520) of a dovetail slot into which the elongated main body slip fits. A bottom (522) of the frustoconical section is spaced apart from a bottom of the dovetail slot.

An actuator is equipped with a body and a slider. Body side rail grooves are formed in side wall portions that constitute the body. On the other hand, slider side rail grooves are formed in the slider. Body side guide rails and slider side guide rails are provided in the body side rail grooves and the slider side rail grooves, respectively. Circular arc grooves serving as ball grooves are formed by body side ball receiving portions of the body side guide rails, and slider side ball receiving portions of the slider side guide rails.

A clamp mount and workpiece alignment apparatus is provided. Clamp including a workpiece alignment apparatus is provided. A method of clamping is provided. The clamp mount and workpiece alignment apparatus is used to mount to a support surface of a workpiece support and for positioning at least one workpiece relative to the clamp while the workpiece is supported on the support surface is provided. The apparatus includes a base, a base mount, a workpiece alignment guide, a clamp mount and an adjustable interface between the base and workpiece alignment guide.
