The name Loup is derived from the French Loup Garou, the human beast who could transform into a wolf; Basically the French version of the Werewolf. The humans who were lou-garous were said to be in contact with the devil himself.
No, kaden, rather obviously it is not. Loup is simply French for wolf, in this case a translation of the Latine word/name Lupus. Loup-garou is in fact a pleonasm (wolf-man-wolf), where the word Loup (wolf) is combined with garoul (old French for werewolf, gar=man, ulph=wolf).
