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.
