Abstract A power transmission device, comprising a lockup clutch (7) for disengaging and engaging a fluid coupling (2), an automatic transmission clutch (3) installed between the fluid coupling (2) and a transmission (T/M), a control device (22) for controlling the disengagement and engagement of the lockup clutch (7) and the automatic transmission clutch (3), and a trouble detection means (70) for detecting that the lockup clutch (7) causes such a trouble that the clutch is seized in engaged state, wherein the control device (22) disengages the automatic transmission clutch (3) when a vehicle stops after the trouble is detected by the trouble detection means (70), whereby an engine stall when the vehicle stops can be prevented. L'invention concerne un dispositif de transmission de puissance comprenant un embrayage de verrouillage (7) destiné à embrayer et désembrayer un couplage fluidique (2), un embrayage de transmission automatique (3) installé entre le couplage fluidique (2) et une transmission (T/M), un dispositif de commande (22) destiné à la commande de l'embrayage et du désembrayage de l'embrayage de verrouillage (7) et de l'embrayage de transmission automatique (3), et un moyen de détection de trouble (70) destiné à détecter si l'embrayage de verrouillage (7) provoque un trouble tel que l'embrayage soit grippé en mode embrayé. Le dispositif de commande (22) désembraye alors l'embrayage de transmission automatique (3) lorsqu'un véhicule s'arrête après détection du trouble par le moyen de détection de trouble (70), ce qui permet d'empêcher le moteur de caler lorsque le véhicule s'arrête.
