couplings for rotary actuation of equipment other than
Fishervalve bodies. This mounting adaptation includes a
flat mounting-surface that is drilled and tapped for
attaching the user-provided bracket. Cap screws for
attaching the bracket are provided. H mounting also
includes an output shaft (with milled flats) to provide
rotary output either directly or through a user-provided
coupling. Dimensional information for the mounting
surface and the output shaft are shown in figure 3.
