I'm 100% positive that they were. Hasbro and Takara cooperate with one another, particularly when it comes to Hasbro's "Transformers" toy line (Hasbro first got the molds from Takara, then Takara re-released their original molds in Japan, under "Transformers" name): so it is more than likely, that Hasbro allowed Takara to use the name of their other franchise and let them do something with it.
