In the improvement of the invention the hub is provided with an axial keyway through which the securing nut is passed into the limited access space. Once the shaft is engaged with the hub the nut is then engaged with the thread on the shaft and tightened using a special tool extending through the centre of the shaft. The tool is withdrawn after use. The nut may be undone and retrieved in an opposite operation.

Abstract: A coupler assembly for axially coupling a hub onto a shaft includes a latch assembly that prevents a locking collar from latching to the hub in a released or disengaged position when the shaft is in the hub. The collar latch assembly includes a latch ring biased eccentrically about the hub and release members when in a released position so as to engage a surface of the hub. When the shaft is inserted into the hub, the release members move to a radially outward position and center the latch ring on the hub. This allows the collar to slide by spring force to a locked position in which the locking members are moved radially inward to engage recesses in the shaft. The release members remain in the radially outward position as long as the shaft is in the hub, thereby preventing the locking ring from engaging the hub and locking the collar in the released position while the shaft is engaged with the hub.
