The Adapter shield says that it contains 74HC541 buffers. I can't read the part numbers from the photo.
There does not appear to be a schematic or a manual.
There are not enough pins on a UNO for the 8080-16 Parallel interface used by your TFT display.
Which means that an Adapter is going to use some tricks. e.g. use a latch.
Without a manual or knowing what i.c.s are on the pcb we have no idea.
I suggest that you buy a "Uno Display Shield" if you want to use a Uno.
Or buy a "Mega Display Shield" if you want to use a MEGA2560.
Or buy a "40-pin Adapter Shield for Mega2560" + "TFT320QVT_9341" + "MEGA2560"
If you have already bought the "ACM UNO ADAPTOR SHIELD FOR LCD" and the "TFT320QVT_9341" please Google for Adapter Manual and schematic
