Methods and apparatus to adjust operation of a fluid flow control assembly are disclosed. An example safety valve controller apparatus includes comparator circuitry to compare a current measurement to at least one of a first threshold associated with a first flow setting of a fluid flow control assembly or a second threshold associated with a second flow setting of the fluid flow control assembly, and determine a first drive signal associated with the first flow setting or a second drive signal associated with the second flow setting in response to satisfying a respective one of the first or second thresholds, and current modulating circuitry to determine a third drive signal based on the current measurement, the third drive signal to modulate the flow setting of the fluid flow control assembly between the first and second flow settings.
