FAN BLADE ASSEMBLY AND COUPLING ABSTRACT A fan blade is adjustably connected to a power driven shaft by means of a hollow coupling with a flat bearing surface on its inside face, and surrounding a hole through its radially outer face. The fan blade shank extends through the hole and is captured by a split ring that has a rim which is compressed against the inside bearing surface by a shoulder on the shank. A removable yoke is held against the blade shaft or shoulder by bolts which pass through the coupling's radially outer face, span the rims and shoulder, and engage into tapped holes in the yoke.
