 The problem is the register, the distance between the lens mount flange and the focal plane (film or sensor being mounted at the focal plane). Nikon is known for having one of the longest register for SLRs and the shortest register for mirrorless cameras. Thus mounting any other lens on a Nikon F mount body will result in an inability to focus at infinity without an optical element in any mechanical adaptor. 

Mounting a Canon FD lens on a Nikon body will require an adaptor with an optical element. Unfortunately this will have a negative effect on the image projected. As has already been mentioned, the mechanical linkages between camera and lens will not be compatible either requiring not only manual operation but stop-down metering. If this is all acceptable then by all means try the Wurth adaptor but personally, I'd give the whole idea a miss. 

With Nikon mirrorless the exact opposite is true, virtually any lens from any manufacturer can be mounted and will focus at infinity. Mechanical linkages will still not work, except for Nikon lenses, and metering may or may not require stop-down action. If the idea is to use the Canon lens, fitting it to a Nikon Z mount body will be the best option.

You can find register distances here.
